2. What is the specific weight of water at 17 degrees Celcius at sea level in...
At sea level, water boils at 100 °C, and the absolute atmospheric pressure is 101 kPa. As the atmospheric pressure above water decreases, the temperature required for boiling also decreases, at a rate of 3.1 kPa per "C. For the system shown below: a. What is the absolute atmospheric pressure at an elevation of 4100 m, assuming a constant unit weight of air of 11.80 N/m3? b. What will be the boiling temperature for water at this elevation? Elev. =...
an iron cylinder with a mass of 25.0g at 105 degrees celcius is placed in a beaker containing 25.0 ml of water at 25 degrees celcius. Assuming that no heat is lost to the surroundings, what will the final temperature of the water bne? the specific heat capacity of iron = .449 j/g degrees celcius and water = 4.18
If you combine 350.0 mL of water at 25.00 degrees Celcius and 130.0 mL of water at 95.00 degrees Celcius, what is the final temperature of the mixture? Use 1.00 g/mL as the density of water.
A 25.00 gram sample of an unknown metal initially at 99.0 degrees Celcius is added to 50.00 grams of water initially at 11.1 degrees Celcius. The final temperature of the system is 20.15 degrees Celcius. Calculate the specific heat of the metal. (The specific heat of water is 4.184 J/g*C). JgoCJgoC
A 25.00 gram sample of an unknown metal initially at 99.0 degrees Celcius is added to 50.00 grams of water initially at 9.47 degrees Celcius. The final temperature of the system is 20.15 degrees Celcius. Calculate the specific heat of the metal. (The specific heat of water is 4.184 J/g*C). Record your answer in scientific notation using three significant figures.
The volume of SO2 collected by water displacement at 18 degrees celcius and 1500 mmHg is 5 L. What is the volume at 35 degrees celcius and standard pressure?
778- j of heat is absorbed by 155 g of water at 34.2 degrees celcius. What is the temperature of the wwater after absorbing the heat
(1 point) Sea Level 3 A heavy box with a height of A = 0.99 m and width of B = 0.85 m is submerged C = 9 m below sea level. In this problem, sea water has a density of 1000kg/m3. 1. Calculate the net normal force on the right side of the box if the box is completely sealed and contains air with atmospheric pressure 2. Find the location of the pressure centre FN = Depth-9.4m kN m...
Your 200g cup of coffee is boiling hot (100 degrees celcius). You throw in 50g of -15 degrees celcius of ice to cool it off. Assuming negligible heat leaves the coffee-ice system during this process, what is the final temperature of your coffee? (The specific heat capacity of ice is 2.03 J/(g degree C and the specific heat capacity of water is 4.18 and the latent heat of melting for ice to water is 334J/g).
To make ice water, I mix 200 g of water at 25.0 degrees celcius with 100 g of ice cubes at -15.0 degrees celcius. Water density is 1.00 g/cm^3, and the container perfectly insulates the system from the enviroment. Thermal equilibrium is eventually reached. Assume that all the ice must reach 0 degress celcius before any ice begins to melt. (a) determine (i) if any unmelted ice remains, and if so, the mass of the remaining unmeltd ice, and (ii)...
